OPB821Z - Slotted Optical Switch

Download the OPB821Z datasheet PDF. This datasheet also covers the OPB820 variant, as both devices belong to the same slotted optical switch family and are provided as variant models within a single manufacturer datasheet.

Description

Each OPB820S and OPB821Z device consists of an infrared emitting diode (LED, 890 nm center wavelength) and a NPN silicon phototransistor mounted in a low-cost black plastic housing on opposite sides of an 0.080” (2.03 mm) wide slot.

Features

  • Non-contact switching.
  • Four standard aperture sizes for high resolution.
  • Low profile.
  • 0.080” (2.03 mm) wide, 0.250” (8.89 mm) deep slot.
  • Choice of PCBoard or wire mountings OPB820S OPB821Z.

Each device in this series has a 0.040” (1.02 mm) wide aperture located in front of the infrared diode. Phototransistor switching occurs when an opaque object passes through the slot. Devices are offered with 0.275” (6.
